GRAIN-SEPARATOR.

Specification of Letters Patent No. 24,714, dated July 12, 1859.

To all whom it may concern:

Be it known that I, J. L. Boom, of Guyahoga Falls, in the county ofSummit and State of Ohio, have invented a new and use fulGrain-Separating Device; and I do hereby declare that the following is afull,

clear, and exact description of the same, reference being had to theannexed drawings, making a part of this specification, in which- Figurel, is a longitudinal vertical and central section of my invention. Fig.2, is a transverse vertical section of ditto. Fig. 3, is a plan or topview of ditto.

Similar letters of reference indicate corresponding parts in the severalfigures.

This invention relates to an auxiliary device to be applied to grainseparators that separate grain by projecting it against the air, and ismore especially designed to be used in connection with a grain separatorthat was patented by me March 8th, 1859. In this patented machine thesound grain is separated from the light inferior grain in consequence ofprojecting it, by certain mechanism, forcibly against the air, the soundgrain on account of its superior gravity being projected farther thanthe li ht.

The object of the within described invention is to receive the grain,both the sound and the light portions, as it is projected from themachine, and to more fully separate and collect the same into distinctparts, and to graduate the separation as may be re quired.

To enable those skilled in the art to fully understand and construct myinvention I will proceed to describe it.

A, represents a box which is formed of two parallel sides a, a, and oneend piece 6, the opposite end of the box being open. The bottom of thebox is formed of two inclined parts 0, c, the lower ends of which areconnected to two parallel pieces (Z, (Z, which form a narrow spout B,the whole length of the box. Within this spout B, two strips 6, e, aresecured by pivots f, at their lower parts. These strips 6, e, divide thespout B, into two compartments of, b ,-the relative length of which maybe varied as occasion may require by adjusting said strips 6, 6, seeFig. 1, in which two positions of the strips are shown, one positlonbeing in red lines.

The box A, may be constructed wholly of wood, and of any desired lengthas may be required. The box B, is placed at such a distance from themachine as to receive the grain and the sound portion being projectedfarther than the other and lighter portion will fall into thecompartment a of the spout, while the light portion will fall into thecompartment b".--The grain is collected or made to pass into the spoutB, in consequence of the inclined bottom. pieces a, o. The red arrows inFig. 1, indicate the sound and the black arrows indicate the lightgrain.

From the above description it will be seen that by adjusting the strips6, e, the separat ing of the grain may be graduated as desired, that isto say, by adjusting the strips 6, 6, so as to contract the compartmenta*, and correspondently enlarge the compartment 11*, the very best grainonly will enter the compartment a If a. very particular or niceseparation is not required the strips e, 6, may be adjusted so as toenlarge the compartment (6", and diminish Z)", and the best portions ofthe light grain will be mixed with the sound. The spout B, may be placeddirectly over proper receptacles to receive the grain.

By means of this invention the grain is perfectly separated and it willprove a great acquisition especially when applied to my patentedseparator, for if the grain is allowed to fall on a floor the twoportions spread considerably and are liable to become mixed to someextent and besides there is no way of graduating the separation.

In separating grain in this manner, to wit, by projecting it forciblyagainst the air, the separation is due in a measure to the rolling ofthe sound plump grain on the floor, the light imperfect grain remainingin the place where it strikes or not rolling 011 account of itsirregular form. In having the grain fall therefore on a level floor ashitherto the roll ing of the sound grain is prevented as soon as thefloor becomes covered and hence the separation will not be as perfect asit otherwise would be. By my invention it will be seen that the bottomof the box A, is always kept clean, the grain rolling therefrom directlyinto the spout B,-this feature in connection with the adjustable stripsor valves 6, 6, effect fully the desired object.

I do not confine myself to the precise form or disposition of the partsas herein shown, I claim as new and desire to secure by Letfor thesameresult may be obtained by vary-' ing the arrangement, but it isessential that an inclined bottom or flooring be used on which the grainmay fall in order to keep the floor clean or from grain to insure therolling process or feature. The valves 0, or

their equivalent are also essential in order that the separation may begraudated as de- 10 sired.

' Having thus described my invention What ters Patent is The box A,provided with an inclined bottom or flooring and adjustable strips orvalves arranged to operate substantially as and for the purpose setforth.
